Description
Technical field
The present invention relates to the side of the temperature control medium feeding mechanism of a kind of mould for monitoring injection machine
Method and such device.
Background technology
In plastic processing and particularly it is essential that moulding mould (is called for short mould in injection
Tool) carry out corresponding homoiothermic, i.e. by supplying targetedly and deriving heat, producing
Specified temp in journey phase chien shih mould is kept consistently.In order to realize this purpose,
Mould is provided with the passage that fluid (being mostly water) flows through.These passages are also referred to as homoiothermic
Pipeline.Generally, the fluid of isothermal it is provided with to multiple passages so that each passage is supplied by influent stream end
And after mould, converging to the end that refluxes.This distribution of fluid and convergence are generally by wherein setting
The allotter being equipped with such as pressure transducer or flow transducer realizes.The AT of the applicant
12213U1 can be used as example.
But, the homoiothermic pipeline being individually supplied with temperature control medium is also the most universal.In this confession
Answering in mode, pressure or flow transducer are the most often integrated in thermoregulating system.
The accumulation not being perceived as and blocking cause heat budget in mould to change until because of the most inclined
The danger of mold damage from set point of temperature.No matter this is situated between to the supply homoiothermic of indivedual homoiothermic pipelines
The situation of matter is still not always the case, wherein to by the situation of multiple homoiothermic pipelines supply temperature control medium
Problem in the later case is particularly acute, because accumulation and blocking are more difficult to be detected.
The method piled up or block below being used for distinguishing in thermoregulating system is known, it may be assumed that
The flow of one particular point in time is denoted as benchmark by each homoiothermic pipeline.After one time
Between put the flow again recorded in each homoiothermic pipeline, to detect the change in hydraulic system.If
Can determine that the change of the most described benchmark, then can assert that existence is piled up or blocking.
The shortcoming of this method is: the pressure in influent stream end and backflow end must be constant.
As the most recurrent pressure oscillation cannot be taken into account.The most in practice, in order to
Measure flow, it is necessary to mould is also connected on suitable measurement equipment, to reach by interruption of work
Necessary degree of accuracy.

Flowed friction.According to described parameter, it is possible to reliably judge whether to pile up or leakage.Special
Not, described flowed friction does not relies on pressure ratio and flow present in the homoiothermic pipeline.Institute
With, even if described flowed friction is also suitable as characteristic parameter in the course of the work.Furthermore, liquid
Pressure resistance is a value being prone to illustrate and be prone to compare for operator, thus, to behaviour
The training cost making personnel is minimized.
The change of the change of flowed friction i.e. resistance is the most also the feature being well suited for
Parameter.This is particularly suited for when the blocking rapidly of one or more homoiothermic pipelines causes the feelings of danger
Condition.
Additionally, described flowed friction also can refer to Kv value.
In order to make manufacturing cost keep relatively low, can only with a pressure transducer in influent stream end and
A pressure transducer in backflow end measures the pressure drop in homoiothermic pipeline.This embodiment
Also it is applicable when there is the homoiothermic pipeline of multiple parallel connection, because on the loop being arranged in parallel
Pressure drop be the biggest.
In order to particularly accurately determine pressure drop, described pressure drop can be respectively by described homoiothermic pipeline
In two pressure transducers being arranged in series in flow technique measure.
A kind of particularly advantageous embodiment is: at least one flowed friction described and/or described extremely
Few resistance change is displayed on screen.
In order to make blocking or the identification automatization of accumulation, could dictate that: at least one tune described
At least one flowed friction described of temperature pipeline determines at least one scope permitted, and/or for institute
At least one resistance described change stating at least one homoiothermic pipeline determines at least one change permitted
Change scope；When at least one flowed friction described leave at least one license described scope and/
Or the change of described at least one resistance is when leaving the excursion of at least one license described, send
Alarm signal.
In order to determine the scope of described license and/or the excursion of license simply especially, can be
Work and before starting, flowed friction is measured or simulate.
In order to reliably pass on described alarm signal to operator, described alarm signal can be with
Optical mode, send, or as alarm sound acoustically especially by display on screen
Send.
For avoiding causing the product of defective part or the damage of mould due to insufficient homoiothermic
Bad, can set: when alarm signal sends, make injection machine cut off.
As follows for calculating the general formulae of flowed friction:
Wherein R represents that flowed friction, Δ p represent pressure drop, i.e. by the difference of measuring pressure, and Φ table
Show tested volume flow.For determining that other formula itself of flowed friction are also for professional person institute
Know.Such as, the index of volume flow can change, with consider in pipeline that may be present not
Same geometric proportion.
In some cases, and can use it for calculating hydraulic pressure by measuring the temperature of temperature control medium
Resistance improves the degree of accuracy determining described flowed friction.It is also contemplated that comprise it in the calculation
His parameter, such as Reynolds number, viscosity or the compression ratio of temperature control medium.
Water is well adapted for as temperature control medium because of its high heat capacity as a rule, and because of
This is used as temperature control medium at this.But other media or additive can certainly be used.
Generally, temperature control medium feeding mechanism is provided with adjustment or control unit, the most such as according to pressure
Power and/or be adjusted according to volume flow or control.In order to particularly accurately keep pre-constant temperature
Degree, can set in the case: the rated value of the pressure of described temperature control medium or volume flow
Rated value changes to come really according at least one flowed friction described and/or at least one resistance described
Fixed.
Certainly, described adjustment or control unit and analytic unit are logically separate unit,
And can be arranged on without any problems in same physical unit.In modern injection machine, logical
Often both is integrated in a common machine controller.
In order to determine the optimum state of thermoregulating system, can before starting the work by described at least one
Flowed friction is measured as benchmark.If such as cause in loop because piling up or block is several
What change, then can find the change of flowed friction.
Flowed friction or the resistance change of the most current still history can be shown, by
This makes these data be used by operator.
